The Ways to Reduce AC Interface Distortion

- Jul 17, 2018-

The AC interface distortion is caused by the back electromotive force of the speaker being fed back to the circuit through the line. The ways to improve this distortion are:

(1) Reduce the number of circuit stages and appropriately increase the static working current of the circuit;

(2) Select a suitable speaker to make the damping coefficient more reasonable;

(3) Use a large-capacity high-quality power transformer, and appropriately increase the capacity of the filter capacitor, and connect a small-capacity CBB capacitor on the filter capacitor.
